How to Use This Fence Calculator

See Methodology

Our free fence calculator estimates materials and cost for your fencing project. Enter your fence length and style for posts, panels, and total cost.

Posts are typically spaced 8 feet apart for wood and 6-10 feet for vinyl/metal. Number of posts = (length / spacing) + 1.

Covers fence types: wood privacy ($8-$15/ft), vinyl ($10-$25/ft), chain link ($5-$15/ft), and composite ($15-$30/ft).

Most jurisdictions require fences to be set 2 to 10 inches inside your property line, and many HOAs have height and style restrictions. Check your local zoning office and HOA covenants before ordering materials. You should also call 811 to have underground utilities marked before digging post holes — it's free and legally required in most states.

Post hole depth matters more than most homeowners realize. The general rule is to dig the hole one-third of the total post height plus 6 inches. For a 6-foot fence, that means a 30-inch hole — with the bottom 6 inches filled with gravel for drainage before setting the post in concrete. Posts set without adequate depth or concrete will lean within a few seasons.

If you share a fence line with a neighbor, consider a neighbor notification or even splitting costs on a shared fence. Many states have legal provisions for shared fence maintenance and replacement costs. For wood fences, plan a treatment and staining schedule — apply a stain or sealant within the first year and reapply every 2 to 3 years to prevent rot, warping, and UV damage. Local code variations can affect everything from maximum fence height to setback requirements, so always verify requirements in your specific municipality before starting your project.

Frequently Asked Questions about Fence Installation

  • How do I calculate how many fence posts I need?

    Divide your total fence length by the post spacing for your material — typically 8 feet for wood — then add 1 for the end post. For example, a 100-foot wood fence divided by 8 gives 12.5, which rounds up to 13 sections plus 1, totaling 14 posts. Always round up to ensure structural integrity.

  • How much does a fence cost per linear foot?

    Installed costs vary by material: wood runs $8–$15/ft, vinyl $10–$25/ft, chain link $5–$15/ft, composite $15–$30/ft, and aluminum or wrought iron $20–$40/ft. DIY installation can cut 30–50% off these prices, but factor in tool rental, permits, and your time.

  • How far apart should fence posts be?

    Wood fences typically use 8-foot spacing, vinyl and metal panels work best at 6–10 feet, and chain link posts are spaced 10 feet apart. Shorter spacing increases strength in high-wind areas or on slopes, while wider spacing reduces material costs.

  • Do I need a permit to build a fence?

    Most municipalities require a permit for fences over 6 feet tall or those in front yards, with fees typically ranging from $20 to $100. You'll also need to check zoning setback rules — most codes require fences to be 2–10 inches inside your property line. HOAs often have separate approval processes.

  • What is the cheapest fence material?

    Chain link is the most affordable at $5–$15 per linear foot installed, though it offers minimal privacy. Wood picket fencing is the next cheapest at $8–$15/ft. Vinyl costs more upfront but requires virtually no maintenance over its 20–30 year lifespan, which can make it the most economical long-term choice.
